Impact of obesity on surgical site infection following colorectal cancer surgery / 中国感染控制杂志

ABSTRACT

Objective To evaluated the impact of obesity on surgical site infection (SSI)following colorectal cancer surgery.Methods A total of 215 patients undergoing radical surgery for colorectal cancer in a hospital be-tween January 2008 and December 2013 were investigated retrospectively,100 patients were with body mass index (BMI)≥25 kg/m2 (obesity group)and 115 patients with BMI60 mL,58(58.00%)patients’duration of surgery was >220 min ,20 (20.00%)of whom developed postoperative SSI;in normal weight group,30(26.09%)patients had intra-operative blood loss of >60 mL,20(17.39%)patients’duration of surgery was >220 min,8(6.96%)of whom developed postoperative SSI.Intra-operative blood loss and incidence of SSI in obesity group were both signif-icantly higher than normal weight group,duration of surgery and postoperative length of hospital stay were both longer than normal weight group(both P <0.05).Conclusion Incidence of SSI in colorectal cancer patients is high. Obesity,long duration of surgery,and more bleeding are high risk factors for SSI in colorectal cancer patients.
